ECS back and forth

Italian C++ Conference 2019

Posted on June 17, 2019

These are the slides of a talk
I gave at the
Italian C++ Conference 2019 in Milan. The
conference was organized by the
Italian C++ Community.
The goal of the talk was to present the three best known and apparently most
used models for the implementation of a software (either a game or whatever)
based on the entity-component-system architectural pattern.

In particular:

The Big Array: used by entityx among
the others, probably one of the first ECS libraries in C++.

Archetypes: used in the Unity engine, but also by
decs if you’re looking for an
open-source implementation in C++.

Sparse Set: used by EnTT, an ECS library
in modern C++ and of which I’m also the author.

In just 50 minutes I tried to go through the pros and cons of these models
(probably failing in the attempt, but I did my best), hoping to give a grasp of
the topic to those interested.

The talk was also recorded. You can find the full video
here.
Thanks to the Italian C++ Community for the opportunity to show to the world how
bad is my English. :-)

Let me know that it helped
